Police respond to active shooter on west side

City Administrator Mike Davis said four people and the gunman were shot during the incident. Their conditions were not immediately available. The call came in around 10:25 a.m. on Wednesday, Sept. 19.

Multiple sources said the shooting victims were taken to the UW hospital.

Middleton police tweeted out a message that says, "Please lock all doors, stay inside and shelter in place until further notice".

NBC15 was told the suspect walked into the building and opened fire. She says she ran out of the building and hid behind a vehicle. She says it shouldn't be odd that a black woman is knocking on doors in 2018.

Lahmers says the shooting was "totally unexpected".

The woman was seeing being held up as she was taken from Esker Software in Middleton, Wisc., Wednesday morning.

A reporter from Madison.com counted at least 40 police cars and ambulances outside the building, which has been cordoned off. There are 34 stores and restaurants in the center that were temporarily closed, Kautzky said. This information is not confirmed by police.
